Windows 10: Service Host: Local System (2) using between 12 and 35% of CPU time

Hello,
I've been having an issue and trying to deal with it a few times. This has been for at least 2 months.
This so called Service Host is using up a lof of CPU which makes my computer run hotter, louder, and even slower.
I have tried sfc scannow, but takes a lot of time and I believe that it's only a temporary fix until restart.
Another solution I've found is going into "troubleshooter" for Windows Update and it fixed the issue until next restart.
To give some context there is now and then "Windows Modules Installer" popping up in the top 3 list of most CPU intensive tasks.
I do not have any viruses installed. I've scanned thoroughly with Malware Bytes and have Avast running in the background at all times.
I've done the "clean boot" technique, it seemed to work (it wouldn't use my CPU anymore) but I don't know which services to keep disabled or so..





Common sight.
Thank you for anyone who would know how to fix this,
KS.

When you click on the arrow next to it on the left, what 2 services are listed there?
But based on the rest, it seems like Windows downloading or sharing updates.

How to Stop Windows 10 From Uploading Updates to Other PCs Over the Internet

 

If that doesn't help, please post a screenshot of your Update History. Thanks.

 

Thank you for the reactions.

I have a few screenshots here:

for TairikuOkami :





Just to be clear I have already made sure (long time ago) that I wasn't uploading updates P2P:





for dalchina:








I've also noticed this here:


I don't know if this is of interest.

I think that it might have something to do with drivers but not sure once again.



Thanks again for helping me out.

 

Hi, any thoughts on why the top one in Update History is in French, but the others not?

Making the possibly completely unjustified assumption your CPU use is somehow related to this, see:
Cumulative Update KB4032188 Windows 10 v1703 Build 15063.502 - Windows 10 Forums

There's a link to manually download it - you could try that and see what happens until a better idea is proposed.

Also you can compare user experiences in that thread.

There's 1 thread per update in News.

 

When I do Windows Update troubleshoot, this is what solutions it comes up with :

 

I don't know why there is part of my computer in french and other half in english.. althought I've always selected I want my computer in English.




another example of this issue...

I'm installing the update you linked me to right now, I will reply later to see how it turned out.

 

Did you install an English language pack? I guess the base language of your OS is French.

I seem to recall someone mentioning some incomplete replacement of the base language text, but have no idea how common that is. (I replaced US English with UK).

 

Well whatever the issue may be with that I don't mind it that much as I know the 2 languages very well.

System Host: Local System is still using around 13% cpu right now so that didn't do anything unfortunately...

 

There was no guarantee it would... but did it install ok?

I reset windows and it seems to be fixed. I can't believe it *chuckle

Thank you so much

edit: I mean i reset windows update Xd

 

Brink's magic... (administrator). Good..

Hope you're using disk imaging routinely to protect your PC and data- allows you to restore Windows & and disk to a previous good state without technical help, even if your disk fails (=new disk). E.g. Macrium Reflect (free) + its boot medium + external storage for image sets.

 

Actually I am mistaken it is still not fixed. Don't know what happened... it's all back and thriving.
